Generally, machinery consist of various machined parts. One of the element of the reliability for machinery is endurance limit related to fatigue strength. Fatigue test was performed on various specimens machined with several nose radius tips under the same machining condition and on shot peened specimens with small glass beads after machining. Experimental conditions are as follows: machined metal is medium carbon steel (0.45%C), tip of cutting tool is cermet (NX33-Mitsubishi), nose radius was varied from 0.2 - 1.6 mm, machined surface roughness was 6 - 24
